Hippocampal dynamics of synaptic NF-kappa B during inhibitory avoidance long-term memory consolidation in mice

Since the discovery that long-term memory is dependent on protein synthesis, several transcription factors have been found to participate in the transcriptional activity needed for its consolidation. Among them, NF-kappa B is a constitutive transcription factor whose nuclear activity has proven to b...
